ANDing

Is it acceptable to use the ^TO macro in two separate condition lines in a 
given recipe?  E.g...

    :0
    * ^TOregexp
    * ^TOregexp
    some-action

I want to perform an action only upon the existance of two specific 
addresses in the (To|Cc|Bcc) fields.  But those addresses could be in a 
different order every time; I'm not yet crafty enough with regular 
expresstions to be able to do this on a single condition
line.
